Abstract

Background/aim: Alopecia areata (AA) is an inflammatory disease with a genetic and autoimmune basis. Herein, it was aimed to study the efficacy and safety of an immunomodulatory therapeutic agent, diphenylcyclopropenone, while manifesting its association with histopathological features, prognostic factors, and side effects.

Materials and methods: In this retrospective study, 98 patients (60 males, 38 females) with alopecia, who were referred to the Hair Disease Polyclinic at the Department of Dermatology, between 2011 and 2015, were included. Together with medical histories and dermatological examinations, a skin biopsy for histopathological examination was conducted for all of the patients prior to therapy. Therapeutic success was evaluated on the basis of the hair regrowth percentage.

Results: Regarding the overall treatment success, 33 (34%) patients had complete response, 16 (16%) had partial response (between 50% and 99%), 27 (28%) had minimal response (between 1% and 49%), and 22 (22%) were nonresponders. Both sexs were equally represented in the outcome.

Conclusions: There was a significant relation between the severity of alopecia and the treatment outcome (P = 0.038). Patients with AA had significantly better response when compared to those with alopecia totalis and universalis. There was no statistically significant relation with other parameters, such as disease duration, age, sex, atopy history, age of onset, and histopathological features.
